.ECCENTRIC==COUPLING FOR SHAKERS.

SPECIFICATION forming part of Letters Patent No. 284,907, dated September 11, 1883.

Application filed February 13, 1888. (ModeL) To all whom it may concern:

Be it known that I, ALEXANDER SooULLER, of Davenport, Scott county, Iowa, have invented a new and Improved Eccentric-Coupling for Shakers, of which the following is a full, clear, and exact description.

My invention consists of a sliding block and box therefor, contrived in a simple and useful coupling for connecting shakers of all kinds,

and'particularly such asare used in grain-' mills for sifting, screening, bolting, and other like operations, to the shafts for operating them, by means .of eccentrics, which are commonly used for the purpose, my said coupling being simpler, more durable, and less noisy than the connections now employed, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in both figures.

Figure 1 is a perspective view of the improved eccentric-coupling, and Fig. 2 is a perspective of the driving-shaft and the eccentric.

I make a box, consisting of the plate a, to be bolted onto the end of the shaker by its ears I), and a plate, 0, to be connected to a by the screw-rods d and nuts e, said plates having flanges f, forming guides for the sliding blocks g, which I fit therein, and in which I fit the eccentric 71, attached to the driving-shaft i,

said block being bored centrally from side to side and transversely to the plates forming the box. It will be seen that the plates can be accurately fitted to the sliding block by the rods and nuts for enabling it to work firmly with out slack, and can be taken upfrom time to time when the block wears slack, making a simple, substantial, and still-running connection for driving shakers. WVhen the sh aft is horizon- 4'0 tal, and the shaker is also, as it usually is, the box will be attached to the shaker in upright position, so that the play of the block in the box will be vertical, and the box will move horizontally to work the shaker; but if the 45 driving shaft should be Vertical, which is sometimes the case, then the box will be arranged horizontally to give horizontal motion to the shaker, the block also sliding horizontally.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The improved eccentric-coupling for shakers, consisting of flanged plates a c, screw-rods (Z, nuts (2, and sliding block 9, constructed and combined with a driving-shaft, i, and eccentric h, substantially as described. 7
